IMPROVEMENT :IINV WATER-WHEELS,

The Schedule referred to n these Letters Patent and making part of thesame To all whom it `may concern:

gate; second, in the construction of the buckets of the water-wheel; andthird, in the construction and arrangement of the devices for hoistingall the gates at one operation.

In order to enable others skilled in-the art to which my inventionappertains, to make and use the same,'I will now proceed to describe itsconstruction and op era-tion, referring to the annexed drawings, inwhich--v Figure l is a perspective view, and

Figure 2, a horizontal section. c

A represents the upper, and B, the lower part of the casing, betweenwhich the wheel C is placed and moves.

Around, and close to the outer rim of the wheel C, between the casings Aand B, are pivoted the inner ends of four curved gates, D D, which, whenclosed, completely encircle the wheel, and shut o' the water, each onethus forming one-fourth of a circle, and, by their' peculiarconstruction and arrangement, also serve as a scroll for conduct-ing thewater to the wheel, whether they are opened much or little.

The buckets E E, of the wheel, are each shaped on a circle ofthree-fourths the diameter' of the inside face of the wheel, and inlength, one-thirteenth of thecir- They are set, so that when the outeredge is at an anglel of ninety degrees, the

inner edge or issues touch an angle of one hundred and sixteen degreesfrom the centre.

From the outer edge of each of the scroll-gates D, an arm, G, extendsupward, above the upper casing A, and is, at its upper end, connectedwith a rackbar, H,vwhich rests upon the upperside of said casing, andgears with apinion, I, secured to a collar, J, which is placed looselyupon the wheelshaft.. There being four gates, D, there are consequentlyfour of the racks, H, which are placed at ri ght an gles, and confinedby suitable guides close to the pinion I.

A large cog-wheel, K, is secured to the collar J, which wheel gears witha pinion, L, upon au upright shaft, M, having its bearings in a suitableframe, N, om

the casing A, and. is operated by a wheel, O, at its Vupperend. Y

It will readily be seen, that by turning the shaft M, the racks H Hareall operated at the same time, and consequently the gates D D are allfour opened or Vclosed at one operation. Y

Having thus fully described my invention,

Whatl claim as new, and desire to secure -by Letters Patent, is-

1. The combination of wheel C and gates D D, when said gatesaureconstructed and arranged to operate as and for the purpose setforth.

2. The combination and arrangementof the casing AB, 'wheel C, gates D D,buckets E E, racks H H, and pinion I, all constructed and arranged asdescribed, substantially as and for the purposes herein set forth.

ln'testimony that I claim the foregoing as my own,

I aiiix my signature, in presence of two witnesses.

F. O. CLARKE.
